Summary
Vascular calcification (VC) significantly increases heart failure (HF) risk, and HF also promotes VC progression, establishing a bidirectional causal link. Atrial fibrillation partially mediates the VC to HF pathway, suggesting targeted interventions.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Epidemiology
Background:
- Observational studies suggest an association between vascular calcification (VC) and heart failure (HF).
- Previous research lacked robust evidence to establish a causal relationship between VC and HF.
- No Mendelian randomization (MR) studies have investigated the causal link between VC and HF.
Purpose of the Study:
- To comprehensively analyze the bidirectional associations between different VC subtypes and HF using MR.
- To explore the causal relationship between VC subtypes (CAC, AAC, CAVS) and HF subtypes (HFall, IHF, ni-HF, ni-HFrEF, ni-HFpEF).
- To identify potential mediating factors in the VC-HF pathway.
Main Methods:
- Employed bidirectional, multivariable, and mediation Mendelian randomization (MR) analyses.
- Utilized accessible genome-wide association study (GWAS) data for VC subtypes: coronary artery calcification (CAC), abdominal aortic calcification (AAC), and calcific aortic valve stenosis (CAVS).
- Included public GWAS data for overall heart failure (HFall), ischemic heart failure (IHF), and non-ischemic heart failure (ni-HF) and its subtypes (ni-HFrEF, ni-HFpEF).
Main Results:
- VC significantly increases the risk of HFall and IHF; CAVS also increases ni-HF risk, but CAC and AAC do not.
- HF (HFall, IHF) promotes VC progression (CAC, AAC, CAVS), confirming a bidirectional causal relationship.
- Atrial fibrillation (AF) was identified as a partial mediator (21.65%) in the causal pathway from CAVS to HFall.
Conclusions:
- A bidirectional causal relationship exists between VC and HF, underscoring the importance of early VC detection and management for HF prevention.
- Controlling HF can help mitigate VC progression, benefiting overall cardiovascular prognosis.
- Targeting AF may be crucial for blocking the 'VC → AF → HF' pathway, offering a novel therapeutic strategy for HF prevention and treatment.
